- Use the appropriate tables to calculate H for (a) the reaction between copper(II) oxide and carbon monoxide to give copper metal and carbon dioxide. (b) the decomposition of one mole of methyl alcohol (CH3OH) to methane and oxygen gases.arrow_forwardAt what points in the Chapman cycle do photochemical reactions take place?arrow_forward5Assume that the amount of energy needed to raise the average temperature of the atmosphere by 0.4°C is 2 × 1021J. Estimate how much burned fuel would be needed to give rise to this increase, assuming this were the only cause of changes in the earth's temperature. Hint: Assume that coal has an energy density of 24 megajoules per kilogram.arrow_forward
- 7. Calculate the E for a process in which a gas is compressed from 3.4 L to 0.28 L accompanied by the loss of 1.5 x 102 J of energy at a constant pressure of 2.5 atm. (1 L•atm = 101.3 J)arrow_forwardThe conversion of oxygen into ozone in the upper atmosphere is as follow : 3232 O2(g) → O3(g), with ΔH298 = +143kJ at 298K. Cp(O2) = 29.355 J/Kmol; Cp(O3) = 39.2 J/K The enthalpy of formation at 200K is : a. ΔH200 = +142 527J b. ΔH200 = -143 473J c. ΔH200 = +143 473J d. ΔH200 = -142 527Jarrow_forwardEthylene (C2H4) plays an important role in the ripening of certain fruits and vegetables. It is sometimes supplemented under controlled conditions at produce—processing facilities but is also produced naturally by many fruit-bearing plants. Although the actual process by which plants produce ethylene is a complex one, imagine that it is produced by the simple breakdown of glucose according to the equation: C6H12O6 (s) à 3 C2H4 (g) + 3 O2 (g) Given S°= 212.1 J/molK, DG°= -910.56 kJ/mol and DH°= -1274.5 kJ/mol for C6H12O6 (s). a.) Determine the sign of DS° for the reaction. b.) Calculate DS° for the reaction. c.) Using the tabulated DG° values in the appendix, calculate DG° for the reaction. d.) Above what temperature (in °C) is the reaction spontaneous? Hint: you will first have to calculate DH° using tabulated values.arrow_forward
- A large sport utility vehicle has a mass of 2.5 * 10^3 kg. Calculate the mass of CO2 emitted into the atmosphere upon accelerating the SUV from 0.0 mph to 65.0 mph. Assume that the required energy comes from the combustion of octane with 30% efficiency. (Hint: Use KE = 1 /2mv2 to calculate the kinetic energy required for the acceleration.)arrow_forwardA large sport utility vehicle has a mass of 2.5 * 103kg.

(Hint: Use KE = 12mv2to calculate the kinetic energyrequired for the acceleration.)arrow_forwarda 100 g copper calorimeter contains 500 g of water at an initial temperature of 20 degree. what mass of butanol was combusted if the final temprature was 95.2 degree?arrow_forward
- The following processes were all discussed in Chapter 18, “Chemistry of the Environment.” Estimate whether the entropy of the system increases or decreases during each process: diffusion of CFCs into the stratospherearrow_forwardA gaseous hydrocarbon reacts completely with oxygen gas to form carbon dioxide and water vapour. Given the following data, determine Hf for the hydrocarbon: Hreaction=2044.5KJ/molhydrocarbonHf(CO2)=393.5KJ/molHf(H2O)=242KJ/mol Density of CO2 and H2O product mixture at 1.00 atm, 200.c = 0.751g/L. The density of the hydrocarbon is less than the density of Kr at the same conditions.arrow_forwardWrite thermochemical equations for the decomposition of one mole of the following compounds into the elements in their stable states at 25 degree Celsius and 1 atm.a) ethyl alcohol, C2H5OH (l) b) sodium fluoride (s) c) magnesium sulfate (s) d) ammonium nitrate (s) (only letter D)arrow_forward
